Titanium Appcelerator; CommonJS has no method

Question

I'm pretty new to Appcelerator and I tried to import my own commonJS Library. I followed the instructions on

http://docs.appcelerator.com/titanium/latest/#!/guide/CommonJS_Modules_in_Titanium

and created a new file named "logger.js", with the following code:

exports.info = function(str) {
  Titanium.API.info(new Date()+': '+str);
};

Now I simply try so exceute this code with:

var logger = require('logger');
logger.info('TEST TEST TEST');

Just like in the example. He found the the file, but didn't recognize my method and I get the following exception:

[ERROR] :  TiExceptionHandler: (main) [602,602] ----- Titanium Javascript Runtime Error -----

[ERROR] :  V8Exception:     exports = logOutput;
[ERROR] :  V8Exception:     _.extend($, exports);
[ERROR] :  V8Exception: } has no method 'info'

I guess it's so simple but I don't where is my fault.

thanks in advance

Answer 1

Finaly I got it. The problems were I'm using an "Alloy Project", just like "Alejandro F. Carrera" mentioned it. I simply have to use Alloy.createController(); to get it work.

var logger = Alloy.createController('logger');
logger.info('TEST TEST TEST');

now it work.

Thanks to all of you to pointing me to the right direction
